Who makes the best custom case?

So a fully custom instrument is being built for me right now by Mr.Chris Stambaugh, and my body style is somewhat unique, the bass will be some what like a hyper bass, but it will also be headless and 33' scale, Chris offers a TKL hardshell with his instruments, but Im getting a little skeptical if it will be snug enough for my bass. So my question is this, who makes a decent custom hardshell case, I dont wanna spend TOO much, also if you ordered a case from this person what is there process like, do they need the bass at hand or anything like that?
